1. Snip cuttings at least a few inches in length with three or more leaves. Caveat: Not all plants can grow from cuttings.

If you wish to add a new plant to your gang, you can buy cuttings from Etsy or eBay sellers, or you can ask friends and neighbors for cuttings.

2. Root your cuttings in water (no root hormone is needed). It's that simple. Tradescantia zebrina cuttings root in less than a week. I recommend waiting at least two weeks for roots to establish before planting them in soil.
